Google has a lot of information and much of it wrong. You're living under your parents roof. Call your mom and tell her how badly you are feeling. Severe is something to look into a lot of the time but it would normally persist if it was an appendix issue. My son has a slow bowel. He was having bowel movements but was still constipated. It caused pain and our pediatrician was unsure if it was appendicitis or not. X ray showed it was his own fecal matter blocking his appendix. My point being, it's not something you just know. You need to tell your mom and have her evaluate if you should see a doctor. good luck
